So i have this 5.3 in a 50 AD pickup.. and doesnt have the vortec cover . i have one.. but seems i am missing the mounting plate to attach it to the motor. Anyone have photos of what i am looking for and how i should be mounting it. I suppose i have to go to a junkyard to find this piece as i dont see any covers with this for sale. sure appreciate help on this . GP

This should be what your looking for, my intake is mounted backwards so it is towards the front of the engine. I mounts with 3 bolts using a 10mm hex head into brass inserts in the intake manifold.

so wait.. the cover has like one bolt. i assume that fits in the hole on the intake and that metal plate with the three bolts somehow supports it? I dont recall that metal plate on my engine.. i suppose thats what i am missing. Will recheck.

So having trouble with this still. I got a mounting plate and it seems to only have two of three holes to attach to the intake?? I will get some photos. But then when i put plastic cover on.. the one bolt in the cover has nowhere to screw the bolt into. Maybe this motor does not have a cover?

Bolt that is like part of the vortec cover itself.. the single bolt. Doesnt line up with anything i can see on the motor/intake. I suppose the cover is not the right one but its a 5.3 motor... from a savannah van. i really only see two places where anything can bolt to intake. will get some photos.

I went and pulled mine off to show..as you can see there are the 3 bolts in the back that hold the bracket on..look about 6" in fromt of the bracket and you'll see the mounting boss sticking up..it has the brass threaded insert in it....a van engjne may have never been designed for a cover..you might can fab a bracket of some sort for the front bolt...

I went back and looked at the pic of your engine...there appears to be a bolt in the hole for the cover..mine was that way..cover and mount got broke in the wreck it came from..they gave me a new cover and mount

i dont see that riser for the cover bolt.it looks like there is just a plug there where the riser should be. if you got a riser from a wrecked manifold you could try epoxy to see if you could glue one on. the used truck manifolds are pretty cheap cause guys replace them with a shorter manifold or an aftermarket manifold. they are easy to replace and the only coolant you may lose is in the heat lines to the throttle body. those can be pinched off easy. some guys even re-use the gaskets. if you got a deal on a manifold it would be easier to swap than spending time fabbing up a bracket or whatever, and also you would get a chance to check the knock sensors under the mnifold. they are in a well and always rust out and give issues because water collects in the well due to poor/hard grommets. you should also replace the short wiring harness connected to them because you get new grommets then. check some engine swap sites or speed shops, maybe somebody has one for cheap.
below is a few pics of what it looks like
